Which engine powered the 2006 Chevrolet TrailBlazer SS?

The 2006 Chevrolet TrailBlazer SS was powered by a 6.0-liter LS2 V8.

Chevrolet introduced the TrailBlazer SS as a high-performance version of its midsize sport utility vehicle. Rather than using the standard TrailBlazer’s six-cylinder engine, the SS received the LS2, a performance-oriented V8 also associated with other General Motors vehicles of the period.

The 6.0-liter engine gave the TrailBlazer SS substantially greater performance than regular versions. The model also received chassis and suspension changes intended to improve handling, including a lower ride height and performance-focused tuning. Rear-wheel drive was standard, while all-wheel drive was available.

The LS2 name can cause confusion because General Motors used several similarly sized V8 families and engine codes. The TrailBlazer SS specifically used the 6.0-liter LS2 for its early production years, including 2006; later model-year details and related SUVs may involve different engines or specifications.
